PHP does this type conversion for you automatically based on the context in which a variable is used. It also allows you to store a different kind of value in the same variable without any explicit type conversion at a later point. You don't have to specify the type of value that you will store in a variable beforehand. PHP, on the other hand, has somewhat relaxed rules around types. A language like C++ needs you to specify the type of variable before you can start using it and won't implicitly convert it to some other type. For example, some of them could have an integer value, while others could be a string or float.ĭifferent programming languages have their own sets of rules for defining and declaring variables. These variables might store the same or different types of data. In summary, if cast is invalid, the output will default to null.When you are writing a program, you will need to create and manipulate multiple variables. If the value is already a integer, the result will remain the same.Īll Type filters work in a similar fashion. StringĪttempts to convert a value to string. If the value is already a integer, the result will remain the same. IntegerĪttempts to convert a value to integer. If the value is already a decimal, the result will remain the same. DecimalĪttempts to convert a value to decimal. Filter will also accept “on“, “enabled“, “yes“, “off“, “disabled“, or “no“. If the value is already a boolean, the result will remain the same. BooleanĪttempts to convert a value to boolean. Liquid Type filters allow devs to cast values unto desired types for logic or information presentation purposes. The blog post was written because sometimes, you may lose sanity trying to cast values/variables to the right types, while extending your Portal templates.
